Ingredients

For the Shortbread Dough

• 2.5 cups flour of your choice

• 2 cups date sugar (adjust to your sweetness preference)

• 100g butter or coconut oil, softened

• 2 whole eggs

• 1 teaspoon psyllium husk (or 2 to 3 tablespoons ground flaxseed, to perfectly bind the dough)

• 1/2 teaspoon salt

• A generous dash of ground cinnamon

For the Jammy Peach Filling

• 3 kg fresh peaches, pitted and sliced

• 1/2 cup date sugar

• 1/2 tablespoon rice flour (the secret to a perfectly thick filling)

• A handful of washed raisins

• A splash of pure vanilla extract

• Grated walnuts (optional, to sprinkle inside the tarts)

How to Make Your Rustic Tarts

Prepare the Dough
In a large mixing bowl, combine all of your dough ingredients—the flour, sugar, butter or coconut oil, eggs, psyllium husk (or flaxseed), salt, and cinnamon. You can mix them together in any order. Work the mixture until it forms a smooth, slightly rich dough with a texture similar to soft modeling clay. The psyllium husk or flaxseed is a wonderful addition here, as it keeps the dough beautifully bound and prevents it from becoming too brittle.

Chill to Set
Once your dough comes together into a smooth ball, wrap it gently and place it in the refrigerator. Let it chill for about 30 minutes. This resting period makes the dough much easier to roll out and shape later on.

Simmer the Peach Filling
While the dough is chilling, place your sliced peaches into a large pan over medium heat. Sauté them for 20 to 30 minutes until they become soft, fragrant, and slightly jammy. Stir in the washed raisins, date sugar, and vanilla extract. Once the mixture begins to gently bubble, sprinkle in the rice flour. This is a brilliant little trick: the rice flour absorbs the excess moisture from the peaches, ensuring your tart crust stays crisp and never gets soggy.

Shape the Tarts
Take your chilled dough out of the refrigerator. Using a rolling pin, roll the dough out on a flat surface and cut it into small squares. To assemble, you can sprinkle a tiny pinch of grated walnuts into the center of each square—this acts as an extra barrier to soak up any remaining fruit juices. Spoon about two tablespoons of the warm peach filling directly on top of the walnuts. Gently fold and pinch the edges of the dough up around the filling to form charming, rustic little nests.

Bake to Perfection
Arrange your shaped tarts on a baking tray and place them into an oven preheated to 170°C–180°C (about 340°F–350°F). Bake for approximately 30 minutes. Keeping the temperature slightly lower allows the tarts to slowly dry and bake rather than brown too quickly. This slow-baking method condenses the peach filling into a rich, dense jam and turns the dough into a delightfully crunchy, buttery shortbread.

Cool and Serve
Once baked, remove the tarts from the oven and let them cool completely. Serve these delightful, rustic treats on a beautiful wooden board or an old copper tray tied with a bit of baker's twine for that perfect cottage aesthetic. Enjoy every delicious, peachy bite!
